LOOK FOR UMBBELLAS OR THE LIKE.

Application filed May 4, 1914.

To all whom it may concern:

Be it known that I, GrUsEPPE FILIPPI, residing at Turin, Italy, have invented certain new and useful Improvements in Looks for Umbrellas or the like, of which the following is a specification.

This invention relates to a safety device by means of which bicycles, umbrellas or the like may be locked so that they cannot be disengaged without using the proper key corresponding to the device. In the annexed drawings a construction of said apparatus is shown by way of example.

Figure 1 shows in plan the manner in which the device is arranged on a stand; Fig. 2 shows the device in open position; Fig. 3 shows the same device in closed position; Fig. 4c is a similar view in which the lock has been removed; Fig. 5 shows the same apparatus, the key barrel being in section, Fig. 6 is a transverse section on line a:m, Fig. 3, Fig. 7 is a longitudinal section on line yy Fig. 4, Fig. 8 is a side view of a form of key, Fig. 9 shows the same key in plan.

The device is inclosed in a box 1, said box being adapted to be mounted on a suitable stand in such a manner as to leave a recess 2 in which is inserted the article to be locked, for example, a stick 3, or the front tube of the frame of a bicycle, or the like.

The device comprises mainly a lock held by a spring in closed position and controlled by a key which moves endwise in a suitable barrel.

In the construction shown in the drawings, the lock bolt 4 is mounted on an arm pivoted in the box and acted on by a spring 7 A lever 9 is pivoted in the box and is carried by the arm 11 projecting into the recess 2; said lever is held by spring 32 in the position shown in full lines in the figures.

The barrel 14 for the key is arranged longitudinally in the box, said barrel being suitably shaped in order to receive the key 15 which may have any desired section. This key is provided with teeth on one of its sides and with a notch 15 on the opposite side.

A tooth 9" carried by the arm 9 of the lever 11-9' is forced by a spring 32 into the notch 15" of the key 15' when this latter is fuly inserted (position shown in Fig. 2). The lever 5, which carries the lock 4 and is acted on by a spring 7, is provided Specification of Letters Patent.

on its lower side with a pin 22 intended to project into the path of the key 15 through a slot 21 of the barrel 14 so that the key 15 actuates the lever 5 with its front end.

The rack provided on one of the edges of the key engages with a pinion 23 on which acts a spring pawl 24: and the barrel 14: is cut away at 25 in order to allow the rack to engage with the pinion.

The pinion 23 carries a projection 26 resting against the lever 5 when the key is removed from its barrel, in order to prevent displacement of said lever 5 and hold the lock t in closed position (see Fig. 3). The same pinion 23 may carry another projection 27 intended to engage another notch 28 in the key so that each device may be Iadapted to be actuated only by its proper A flat spring 29 is preferably mounted on the upper side of the barrel of the key, said spring having a recess 30 on one of its edges and a pin 31 at its front end. This pin is intended to project into the path of the key through a suitable hole when the key is removed from its barrel. The spring 29 is raised (Fig. 7) when the key is inserted in its barrel and lowered (Fig. 6) when the key has been withdrawn; in this latter case the tooth 26 of the pinion 23 projects into the recess 30 of the spring 29 so that the pinion 23 is prevented from turning until the proper key has been inserted.

The operation of the device is as follows:-The key when fully inserted in its barrel is locked by the projection 9 of the arm 9 engaging its notch 15". By arranging the article to be locked in the recess 2, the arm 9 is caused to approach the wall of said recess so that the arm 11 moves out of engagement with the notch 15 of the key. Then, on the key being withdrawn, the lever 5 actuated by the spring 7, carries the lock 4 into closed position and at the same time the pinion 23 is actuated by the key meshing therewith, so that the tooth 26 comes in engagement with the lever 5. On the contrary when the key is inserted in its barrel the lock is released because of the rotation of the pinion 23 and then the key acts with its front end on the pin 22 (Fig. 2) so that the lever 5 and the lock 4 are brought in open position.

In this construction the key acts directly to control the various parts of the device,

including the lock l and the projection 26 intended to prevent the lock from any dis placement when in closed conditiomand is itself directly engaged by the stop 911 when in inoperative condition.

What I claim as my invention and desire to secure by Letters Patent is l 1. In a safety device for locking umbrellas, bicycles, or the like, the combination with a casing having a recess in which a part of the article to be locked can be inserted and means controlled by a key for closing said recess, of a lock bolt pivoted in said casing, a spring for holding said lock bolt in closed position, a projection on said lock bolt extending into the path of the key,

a barrel for the key, a key slidablein said barrel and adapted to act on the projection of the lock bolt, means adapted to engage the key directly, said means being controlled by the article being inserted in the recess of the box, and means actuated by the key for carrying a stop into engagement with the lock bolt when this latter is in closed position.

2. In a safety device for locking umbrellas, bicycles, or the like, the combination with a casing having a recess in which a part of the article to be locked can be inserted, of a lock bolt pivoted in said casing, a spring for holding said lock bolt in closed position, a projection on said lock bolt extending into the path of the key, a barrel for the'key, a key having a notch on one edge 1nd slidable in said barrel in such manner as toshift the projection of the lock bolt, a

lever one end of which normally engages the notch in the key while the other end is shifted by an article being inserted in the recess of the casing, and means actuated by the key for carrying a stop into engagement 7 with the lock bolt when the latter is in closed position.

3. In a safety device for locking umbrellas, bicycles, or the like, the combination to engage the key directly, said means being controlled by the article being inserted in the recess of the casing, a pinion'meshing with the teeth of the key, and a stop on said pinion engaging the lock bolt when this lati ter is in closed position.

4:- In a safety device for locking umbrellas, bicycles, or the like, the combination with a casing having'a recess in which a part of the article to be locked can be inserted, a lock bolt pivoted on said-casing, a

spring for holding said lock bolt in closed position, a projection on the lock bolt extending into the path of the key, a barrel for the key, a key toothed on one of its edges 7 and slidable in "said barrel, means for, en

gaging said key controlled by the articlebeing inserted into the recessof the box, a

pinion meshing with the teeth of the key, a

stop provided with a recess and mounted on' V said pinion and adapted to engage the lock bolt when in closedposition, a fiatspring on the barrel forthe key, said spring having a recess corresponding with the stop I when this latter is in locking position, and a projection on said spring extendingrinto the path of the key so that when the key is removed from its barrel the spring engages the stop which in turn engages'the look.

In testimonywhereof I have signed my name to this specification in the presence of two subscribing witnesses; r

Witnesses MARIO Tos'r PIERO GIANOLIO.
